In our upcoming October Sequences gathering, we will discuss the essay "Use the Try Harder, Luke," which examines the necessity of applying deliberate, focused cognitive effort to dissolve confusion. To prepare for this, it is worth looking at the history of debugging complex, high-impedance systems and how engineers establish a baseline of diagnostic tension.
In the mid-nineteenth century, telegraph operators laying the transatlantic cable encountered a frustrating phenomenon: signal attenuation. A clear electrical pulse sent from Ireland would arrive in Newfoundland as a slow, smeared whisper. The operators could not solve this by simply staring at the dial or hoping the copper would improve. They had to build a system of diagnostic tension: testing the insulation at regular intervals, calculating the precise resistance of each mile, and using Lord Kelvin's newly invented mirror galvanometer to detect the tiniest changes in current. They had to push past their assumptions about how electricity behaved, mapping the physical constraints of the cable node-by-node. Debugging required a relentless refuse-to-yield focus.
This diagnostic tension is the exact opposite of passive confusion. When we encounter complex obstructions in our lives—whether in our careers, our logic, or our relationships—we default to staring. We wait for the signal to clear, treating our confusion as an external mystery rather than a system to be debugged. To "try harder" is to route the signals, to isolate the nodes, and to push our minds to look directly at the points where we are confused. It is the active engineering of cognitive tension, refusing to let our attention slide into passive overwhelm.
This October, we will explore how to apply this engineering mindset to our own reasoning. We will discuss how to identify the high-impedance joints in our plans, and how to use the collective intelligence of the room to spot the cognitive blocks we are too tired or distracted to push through ourselves.
